Plotting, Smoothing and Growth Trait Extraction for Longitudinal
Data

Assists in producing longitudinal or profile plots of measured
traits. These allow checks to be made for anomalous data and growth patterns
in the data to be explored. Smoothing of growth trends for individual plants
using smoothing splines is available for removing transient effects. There
are tools for diagnosing the adequacy of trait smoothing, either using this
package or other packages, such as those that fit nonlinear growth models.
A range of per-unit (pot, plant, plot) growth traits can be extracted from
longitudinal data, including single time-point smoothed trait values and
their growth rates, interval growth rates and other growth statistics, such
as maximum growth. The package is particularly suited to preparing data from
high-throughput phenotyping facilities, such as imaging data from a Lemna-Tec Scananalyzer
(see <http://www.lemnatec.com/products/hardware-solutions/scanalyzer-3d> for more
information). The package 'growthPheno' can also be installed from
